When should a departure procedure be included as part of the clearance?

A departure procedure should be included as part of the clearance primarily when only written departure procedures are published for the airport. This ensures that all pilots are properly informed about the specific instructions they need to follow during takeoff, particularly when there is no radar service available to provide guidance. Written departure procedures are essential in such scenarios as they offer standardized instructions aimed at enhancing safety and efficiency during departures.

In situations where no radar services are available, it is crucial for the clearance to contain detailed procedures to prevent confusion or deviations during takeoff. Poor weather conditions can also necessitate the use of departure procedures, but this is more of a situational consideration rather than a requirement for inclusion in every clearance. While pilots may request specific procedures, the responsibility for including procedures in the clearance lies with air traffic control, especially when only written procedures are established for the airport. Thus, when there is reliance on written departure procedures, it is vital to include those in the clearance to ensure compliance and safety for the departing aircraft.
